A results below were recorded during tensile test for a steel specimen to be used to manufacture water reticulation steel pipes. The diameter of the specimen measured by an electronic vernier was found to be 0.597cm. Other measurements noted were the gauge length of 5.010cm,elongation 0.0635mm at load of 7.11kn, 7.33kn load at the yield point and 8.15kn load at the point of failure. The reduction of the cross-sectional at failure is estimated to be 35.06%.

Y 1.8cm- Y Not to scale Figure 1aarrow_forwardGenerally Ring and ball test is performed on which material ?arrow_forward1.46: A contractor claims that the mean compressive strength for a concrete mix is 5000 psi (μ) and that it has a standard deviation of 400 psi (σ). If you break 20 cylinders (N) and obtain a mean compressive strength of 4,800 psi (m), would you believe the contractor’s claim? Why? (Hint; Use statistical t-test.) Next, what is the maximum number of breaks (N) that could be performed that WOULD make you believe the contractor’s claim? Assume that the results wouldn’t change, i.e. σ = 400 psi and m = 4,800 psi. Recall that the equation to find the lower bound of a one sided distribution is LB = μ - (tσ)* σ/(N^0.5) Because the sample size is relatively small, use the ‘student t test’ to represent the normal distribution. You should have at least 95% confidence in the results. That means that α = 0.05. Keep in mind that this is a one tailed distribution, since we only care about the lower bound (i.e. meaning that we are only concerned about concrete that doesn’t meet our minimum strength…arrow_forward
